DETAQHABLE FASTENER Specification of Letters Patent.

Patented Feb. 6, 1906.

Application filed January 26, 1905. Serial No. 242,761.

To LZZ whom, it may con/cern:

Beit known that I, JULIUs PINcUs, a citizen of the United States,residing at Norfolk, in the county of Norfolk and State of Virginia,have invented new and useful Improvements in Detachable Fasteners andButtons, of which the following is a speciiication.

My invention relates to two-part or detachable buttons and fasteners.

The object of my invention is to provide a quick means for securingcravats, buttonstuds, and the like, which may be quickly applied anddetached.

With these and other objects in view my invention consists in certainadvantages shown in simple embodiments in the accompanying drawings,forming a part of this specification, in which- Figure 1 is a sectionalelevation of the fastening device applied to a necktie or cravat in itslocked position. Fig. 2 is an enlarged view of the fastening device inan unlocked position. Fig. 3 is an elevation of the base memberinclosing the releasing device. Fig. 4 is a plan of the same. Fig. 5 isan interior plan of the resilient convex shell portion of the device.Fig. 6- is an elevation of the invention applied to a detachable ortwo-part button. Fig. 7 shows the locking-prongs or latch-tonguesattached to a stud member. Fig. S is a front elevation of thelatch-tongue or bifurcated member, showing attachments moans forsecuring it to a cravat, button, or stud.

In the drawings, in which like referencenumerals indicate similar partsin all the views, 1 is a disk or back plate of the base member and isprovided with a neck or shank 2, having an elongated slot 3, Fig. 1,passing through it.

4 is a crimped edge or bead provided with an annular channel to allowthe resilient conveX shell or depression surface 5 to be fastenedthereto at its edge in a suitable manner.

6 and 7 are spring tongues or prongs joined to the portions 8, Fig. 1,forming a neck or lug to which the article to be secured thereto isaffixed.

8A is a shield of the cravat or tie 8B and is secured to the portion 8by means which will be described hereinafter.

8C, Fig. 6 is a button provided with the bifurcated or forked portions 6and 7 to render it easily applied to the base portions 1 and 4c l andremoved therefrom rapidly. i

8, Fig. 7, is a stud adapted to the latch-- tongues so as to allow it tobe applied to the base portion and easily removed therefrom in the samemanner as the button 8C.

As already described, the portion S is provided with a bifurcated orforked portion comprised of the latched tongues or springs 6 and 7 andhave wedge-shaped latches or hooks 9 with their shorter sides at rightangles to the longitudinal planes of the tongues 6 and 7, as at 10 inFigs. 7 and 8, and adapted to spring under the disk or plate 1 to holdit and the bifurcated or forked bar S together, as shown in Figs. 1 and6.

11 is a notched presser or detaching block having the lugs 12, Figs. 2and 5, and is attachedto the resilient shell 5 by a screw or rivet 13.The block 11 is provided with curved springs 14, attached thereto at 15and capable of forming a sliding contact upon the disk 1 when the shell5 is actuated by the iinger to release the fastener members and torestore the shell and the block 11 to its initial point, as shown by thecurved dotted lines in Fig. 2.

When the prongs or tongues 6 and 7 are inserted in the elongated cavityor slot 3, it compresses the tongues together by the hypotenuse of eachtriangular-shaped latch 9, due to the compressing infiuence of the slotbringing the tongues together, until the latches reach the unrestrictedspace beneath the disk portion 2 of the base member, at which point thelatches separate and lock the two members by the parts 9 being under thedisk 2, which prevents their pulling out by the flat portions 10. Inorder to separate the members, the shell 5 is depressed, which extendsthe block 11 so that the lugs 12 are brought in contact with the angularsides of the latches 9 suficient to bring them together and allow themto pass into the slot 3 until withdrawn, at which period the two members6 and 7 instantly spread and assume their parallel position, as shown inFig. 8. In order to secure the spring latchtongues Gand 7 to the cravat,I provide separable tongues 16 and 17, Fig. 8, which are insertedthrough the shield 8, Fig. 1, and then attened, as shown.

1S is a screwed lug and serves for the portion S when it is desired toaffix the latchtongues into the button 8C or stud 8D. The

IOO

dotted lines in Fig.`6 show the button 8C separated from the shellmember 5.

I make the shank or neck 2 of a spindleshaped or elongated form to admitof its being readily inserted into the buttonhole of the garment.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s

1. A button or fastener comprisinga beaded ldisk having a shank of anapproximately elliptic cross-section, a rectangular slot passing throughthe shank, a flexible imperforate convex shell member, said beingcrimped to the shell member, fa separable forked latch member adaptedt'o engage the lower surface of the disk, :a fastening -shank on thesaid llatch member7 -a recessed block yattached to and actuated by theconvex shell portion for releasing the latch member from the disk, and aset `of curved independent `springs attached to the recessed block andadapted to bear upon the lower surface kof the disk to restore theconvex shell land the said yblock to their normal positions.

2. A fastener for buttons and the like comprising a perforated diskportion having a rounded edge, a perforated shank having an oval shapein cross-section, a flexible imperforate semispherical shell affixed tothe said rounded edge of the disk, a detachable latch member havingattachment-prongs thereon at one of its ends, a movable recessed blockattached to the said imperforate shell, a set of diverging independentsprings attached thereto and adapted vto bear upon the lower surface ofthe disk when the shell is vdepressed for disengaging the latch member.

In testimony whereof I have hereunto affixed my signature, in thepresence of two witnesses, this 23d day of January, A. D.
